论文摘要
在本文中,我们证明了一个验证某些积分不平等的域(严格地)包含在某些自由边界问题中,或者它与$ n $ - ball的相吻合。我们还提出了新的过度确定的价值问题,这些问题具有$ n $ - ball作为解决方案。为了达到我们的结果,我们使用涉及Dirichlet问题解决方案的域衍生物的整体身份。
In this paper, we prove that a domain which verifies some integral inequality is either (strictly) contained in the solution of some free boundary problem, or it coincides with an $N$-ball. We also present new overdetermined value problems which have an $N$-ball as a solution. To reach our results, we use an integral identity which involves the domain derivative of the solution of Dirichlet problem.
